SIMPLEBUS REMOTE CAMERA MODULE ART. 1259/A
This accessory in the Simplebus range allows modulation and transmission of
the video signal from 3 cameras which can be viewed cyclically on the monitor,
together with the image from the external unit.
Art. 1259/A can be used in Simplebus Kit Simplebus B/W systems (Art. 5714,
Art. 5814) upstream of Art. 4888.
Operation
With the monitor switched on, sequential switching of the TV cameras can be
activated from the video entry phone by means of function keys that depend
on the type of system and the programming of module 1259/A using the
8-way microswitch (S1) as described below. Sequential switching can also be
activated using a clean contact (C-NO) connected to the INA - GND input as
per Diagram SB2V/017G. Sequential switching of the cameras is also possible
in audio mode. Each time the actuator pushbutton on the monitor or the manual
contact is pressed, a camera is activated in sequence as shown in Fig. 1:
(hypothesis of 3 cameras connected, see MODE 1, 2, 3).

Programming the number of cameras connected
The module has 3 coax video inputs to which the cameras must be connected,
occupying the terminals in the first free position starting from the bottom. Select
the number of cameras connected using switches 7 and 8 of selector S1, as
shown in Tab. 1.

1. GENERIC ACTUATOR MODE
NOTE: Before programming the module, see Tab. 3: Compatibility of
1259/A.
Use the Generic Actuator function on a pushbutton of
the video entry phone to control module 1259/A.
In this mode, with the video entry phone monitor
switched on, it is possible to cycle through all the
connected cameras by repeatedly pressing the generic
actuator pushbutton. Microswitch "S1" must be set as
shown in Fig. 2.
2. ACTUATOR WITH CODE MODE
NOTE: Before programming the module, see Tab. 3: Compatibility of 1259/A.
In this mode, module 1259/A can be controlled using an
actuator with code pushbutton. To activate the function,
program the pushbutton on the bracket and set selector
"S1" as shown in Tab. 2.
In this mode, with the video entry phone monitor
switched on, by repeatedly pressing the actuator with
code pushbutton, it is possible to cycle through ONLY
the cameras connected to module 1259/A with the
corresponding address.
In the same system, it is possible to install up to 8
1259/A modules with 8 different codes.

3. SIMPLEBUS KIT MODE
NOTE: Before programming the module, see Tab. 3: Compatibility of 1259/A.
In this mode, the module Art.1259/A may be controlled using the self-ignition/
video request pushbutton in the Simplebus Kit. In the event of self-ignition,
repeated pressing of the self-ignition/video request
pushbutton results in the toggling of images from the
external units installed as part of the system. When
audio mode is activated (by lifting the handset), repeated
pressing of the self-ignition button results in the toggling
of images from the external unit and the remote cameras
(connected to the module 1259/A). Set selector "S1" as
shown in Fig. 4 to activate the function.
THE THREE OPERATING MODES DESCRIBED ABOVE ARE ALTERNATIVES.
4. MODE WITH SWITCHBOARD 1998A
In parallel to one of the modes described above, it is possible to activate the
module by means of a Video Call from the switchboard. The "switchboard"
function is made available by connecting the INA-GND contact to the OUT-OUT
terminals of Art. 1998A , as shown in diagram SB2V/018G.
NOTE: The remote camera module must be connected to the outgoing
Bus line from terminals LM-LM of the switchboard. Set the switchboard to
Video mode before making the call.
Each time a video call is made from the switchboard, the monitor will switch on
as soon as the handset is lifted, and the image displayed will be the one from
the first camera connected to Art. 1259/A. At this point, each time a control
pushbutton is pressed (see previous modes) or each time the manual contact
is closed, a camera is activated in sequence as shown in Fig. 1 (hypothesis of
3 cameras connected, see MODE 4, 5).
5. MODE WITH EXTERNAL AUDIO UNIT ART. 1602
Previous modes 1, 2 and 3 may also be used in a system
which has an audio-only external unit, Art. 1602. When
setting the selected mode, DIP 1 of selector "S1" must
be configured as shown in Fig. 5 and the external unit
in video mode as shown in Fig. 6. Every time a call is
received from the external
unit or when self-ignition
occurs, the monitor lights
up and displays the image
coming from the first camera
connected to Art. 1259/A. At this point, each time
a control pushbutton is pressed (see previous
modes) or each time the manual contact is closed,
a camera is activated in sequence as shown in Fig.
